Hello,

I am having problems in configuring "ntop" on my CentOS 5.3. I have followed all steps which is required as per the documentation.

The installation steps are:-

1) Download the "tar"
2) Extract it.
3) cd to that directory
4) run ./autogen.sh
5) make & make install

I am getting error while executing "make". Below is the error output.

Please help.I already installed RRDTool, libpcap & libpcap-devel package as required for "ntop" installation,but still i found error. My ntop packag version is "ntop-3.3.10".

You need also the rrdtool-devel package in order to compile ntop.

Regards

from the " BUILD-NTOP.txt "
do you have these packages installed ?
--- `/root/Desktop/tar_118/ntop-3.3.10' ---- a big no-no
also you SHOULD NOT be building it AS ROOT!!!!!!!
and you should NOT build it on your root desktop!!!!!!!
that is a MS windows thing ( bad habit ) and WILL cause you all kinds of problems

build it in your NORMAL user home folder or a "build" folder that is owned by your normal user
something like this
/usr/opt/src/ntop
where you have done this to the src folder
where "your user name" is replaced WITH your user name and do NOT ad the ""

then AS A NORMAL user run

My "ntop" installation got success & i can open the ntop page by typing
http://localhost:3000

But, it isn't asking me user name & password for "ntop" authentication. I can login with it.

Another thing is : after login "ntop" is saying
"please make sure that ntop html/ directory is properly installed"

Now, during whole installation,i haven't found any step to configure "html" directory for "ntop"

Please Help.

Advanced Thanks,

Before running ntop for the 1st time, you should run
to create a password for the user admin.
Without it you cannot access the admin pages of ntop.

Using CentOS5.4 Final. Installed ntop using yum. Configured password for admin using ntop -A.
Now while starting the ntop service it is giving the error.

Using service ntop start command.

It looks like the startup options are not parsed correctly. Take a look at /etc/ntop.conf, or try to start it manually using the options in that file

Regards

It just gives error if I start it as a daemon. But if started manually with option --user it works. Yes it is error in parsing the file. But I suppose, I have not edited the file. Its just the default configuration that I am trying to use with. I do not know much about ntop. Have not used it much before but I kind of like the utility.
My main aim is to start it as a daemon and at boot up so that I do not have to keep watch at it much and at the end of the day can go through the logs using the web interface and I am done with log watch.

If you cannot find out what is the problem with the startup options, you can put your ntop command with the correct options in rc.local, i.e:
Cheers

Done that. Let me see if that makes any difference. But is it a bug or something? How do I know that?
